I'm looking to put a 12-25 Ultegra 6700 on my bike, which has so far only done around 70 miles. Will the chain need to be shortened or should it be ok as it is?

    Ok as it is, I swap cassettes and wheels with two different ratio cassettes all the time.

    It depends what cassette you had on before.

    Technically you should check if it needs links removing,for that minimal amount it should be fine though

    It's Di2, so I'm assuming I'd know if there's an issue if the reset doesn't give me perfect alignment?

    Oh yeah, you would be better off shortening it if you are sticking with the 25, no point in having extra chain you don't need.
